COMMAND TO FIND SERIAL NUMBER OF ROUTER/SWITCHES

[pbarman]

ARE THERE ANY COMMANDS WHICH WILL GIVE THE CHASSIS SERIAL NUMBER AS OUTPUT, FOR ROUTERS? ALSO, IF ANYONE KNOWS A COMMAND FOR SWITCHES THAT WOULD BE HELPFUL.

Show version

[Aaron Ekinaka]

Just to be extra confusing, the Cisco Small Business line of switches (SG300, SF300, etc) use a different command to display the serial number:

show systemid

There is a show version command, but it does not include the serial number for whatever reason.

Thanks alot, I have SG300 and yesterday searched about 3 hours to find the serial number. Show System id was the right one.

[PaulSmith]

Wrong, the correct syntax is 'show system id'

Thanks @PaulSmith , this help me a lot in finding the serial no without going to each floor.

This is a very old discussion and demonstrates that depending on platform and version of code that there are several answers that might be correct. It is an example of what a wonderful resource this community is.

The "show version" command will display the Processor board ID, which is the serial number. You can verify with the "show inventory" (this is as of 3.16.04b.s).

Glad I didn't wait 16 years for this!

show ver should work for most switches

In CAT4006 running older code, sh ver will not give the correct serial number. You can use "sh sprom chassis". If you have a CAT6000 running native IOS, you can use "sh idprom all"

For routers, try using "show diag". You could also use SNMP to gather serial numbers

[mmarcus]

sorry to say , the show ver on routers will not show you the serial number related to the router

[ttuncaral]

show version shows processor board ID not the chassis number.

Some new model of routers with newer release of IOS show chassis number by using SHOW SNMP command. you can define it in router configuration by using SNMP CHASSIS for older releases and devices.

"Show inventory" command should work.

After 13 years I think the original poster might have figured it out. :)

LOL.. I am noticing the time now.. It might not be helpful for the poster but might be helpful for someone who is searching for it now.. :)
